REAL WORLD TAKEAWAYS

• When you go outside, the air sometimes feels warmer than the temperature suggests. This is especially true the more humid the air is.
• Humidity is a measure of the amount of moisture in the air. Humidity and air temperature combine to create the heat index, which some people refer to as the “feels like temperature.”
• A high heat index can be dangerous, even deadly. While the index increases with both the air temperature and humidity level, it increases especially quickly as the humidity rises. The more humid the air is, the harder it is for the body to dissipate heat via sweat.
• As global temperatures rise, more and more cities will experience deadly heat waves. Local leaders have an important role to play in keeping their residents safe during hot and humid days.
